In this photo taken Tuesday, Aug. 20, 2013 in Johannesburg Robohand inventor Richard van As, shows hands that he has made for people in his workshop at his home. Van As, who lost four fingers to a circular saw two years ago decided to build his own hand after seeing a video posted online of a mechanical hand made for a costume in a theater production by designer Ivan Owen in Seattle USA. Van As and Owen invented the Robohand that uses cables, 3D printing, screws and thermoplastic and has fitted about 170 people with robohands. (AP Photo/Denis Farrell)
